Description

Technical Field

[0001] The utility model relates to a manual-automatic integrated sliding block structure. Background Art

[0002] The application fields of plastic products are becoming wider and wider, the types of products are becoming more and more, and at the same time, the structure of products is becoming more and more complex, which leads to more and more complicated mold structures.

[0003] In the insert injection molds that are widely used in the market, the following are used: Fig.11 The slider structure shown includes a slider body 20 having a drive groove 204 adapted to accommodate a shovel machine 30. The shovel machine 30 is connected to an external power source and pushes the wall of the drive groove 204 to drive the slider body 20 and the insert on the mold to complete the mold closing and opening actions.

[0004] The traditional passive mold closing process has the following problems:

[0005] (i) When the shovel 30 pushes the slider body 20 toward the insert to close the mold, the insert may be misaligned with the predetermined mold closing position due to the vibration of the slider body 20, which increases the risk of damaging the insert and the mold during the mold closing process, thereby resulting in high subsequent maintenance costs and low product yield;

[0006] (ii) Since the shovel 30 is adapted to the driving groove 204 on the slider body 20, during the actual mold closing process, there is a possibility that the shovel 30 moves and collides with the slider body 20, which has an adverse effect on the safety and production efficiency of product processing. Utility Model Content

[0007] The utility model provides a manual-automatic integrated sliding block structure, which can effectively solve the above problems.

[0008] The utility model is achieved in this way:

[0009] A manual-automatic integrated slider structure comprises a guide seat with a slide buckle fitted on one side of a mold, a slider body fitted with the guide seat slide buckle, and a shovel located on the slider body on the side opposite to the mold;

[0010] The slider body has an insert fixing block facing the mold side for aligning and inserting the insert in the preset position; the slider body is provided with an avoidance groove for avoiding the shovel machine in the direction away from the mold, and the groove walls on the opposite sides of the avoidance groove are slidably provided with linkage blocks that are in contact with the back mold surface of the shovel machine;

[0011] The shovel moves upward, and the back mold surface of the shovel pushes the linkage block that is in contact with it, actuating the slider body to slide away from the mold to complete the mold opening action; when the shovel continues to move upward until it is separated from the linkage block, it pushes the slider body toward the mold to complete the mold closing action.

[0012] As a further improvement, the insert fixing blocks on the slider body are provided in plurality, and the number of insert workstations on the mold body is provided corresponding to the fixing blocks.

[0013] As a further improvement, the slider body slides in the sliding groove on the guide seat, guide blocks are provided on the bottom of the two opposite sides of the slider body, and guide grooves are provided on the two opposite groove walls of the sliding groove for slidingly cooperating with the guide blocks to guide and limit the slider body.

[0014] As a further improvement, linkage grooves for sliding cooperation of the linkage block are provided on the groove walls on opposite sides of the avoidance groove, a limiting block with a cross-section larger than that of the linkage block is fixedly connected to the rear end of the linkage block, and a limiting groove which is communicated with the linkage groove and for sliding cooperation of the limiting block is provided on the avoidance groove, and a pressing spring is installed in the limiting groove, which contacts and presses the limiting block so that the linkage block has a tendency to extend out of the linkage groove and contact and cooperate with the back mold surface of the shovel.

[0015] As a further improvement, the actuating portion of the shovel machine is provided with reset guide surfaces on both sides of the mold surface for sliding the linkage block open.

[0016] The beneficial effects of the utility model are:

[0017] The present application transfers the control of the slider structure's mold closing action to on-site operations through the collaborative movement of a transfer-type insert fixing block, a slider structure, a shovel machine, a linkage block, etc., thereby making it compatible with a wider range of application scenarios; the slider structure is provided with two action modes, namely, manual mold closing and automatic mold opening, which solves the difficulty of mold damage and product scrapping caused by insert vibration and dislocation during passive mold closing of the traditional slider structure, reduces production costs, improves production efficiency and the safety of the production process, and greatly improves the product yield rate.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0036] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] A manual-automatic integrated slider structure, such as Figure 1 , Figure 2 , Figures 4 to 6 As shown, the slider structure is arranged on one side of the mold 40. The slider structure includes a guide seat 10 that is slidably engaged with one side of the mold 40, a slider body 20 that is slidably engaged with the guide seat 10, and a shovel 30 located on the side of the slider body 20 that is away from the mold 40. The slider body 20 has an insert fixing block 24 that is aligned and inserted with the insert 50 at a preset position on the side of the mold 40; the slider body 20 is provided with an avoidance groove 201 for the shovel 30 to be raised and lowered in a direction away from the mold 40, and the groove walls on opposite sides of the avoidance groove 201 are slidably provided with linkage blocks 21 that are in contact with the back mold surface 322 of the shovel 30; the shovel 30 moves upward, and the back mold surface 322 of the shovel 30 pushes the linkage block 21 that is in contact with it, actuating the slider body 20 to slide in the direction away from the mold 40 to complete the mold opening action; when the shovel 30 moves upward to be separated from the linkage block 21, it pushes the slider body 20 in the direction close to the mold 40 to complete the mold closing action.

[0038] Such a design can effectively avoid the situation in which the insert 50 is vibrated and misaligned due to the shovel 30 serving as a power source during the traditional mold closing process. Furthermore, when the slider body 20 is manually pushed for mold closing, if the operator finds that the slider body 20 cannot be pushed smoothly, it means that the insert 50 is loose and deformed. The operator can simply handle and solve the problem according to the specifications (i.e., replace the insert 50 at the workstation before performing the mold closing action) without having to stop the machine and wait for professional technicians. In addition, damage to the insert 50 and the cavity of the mold 40 during automatic mold closing can be avoided.

[0039] Furthermore, if Fig.11 As shown, the driving groove 204 on the conventional slider body 20 is arranged to match the shovel, which results in the risk of the shovel 30 moving and hitting the slider body 20 during the mold closing process.

[0040] like Fig. 9 , Fig.10 As shown, in the present application, since the air avoidance groove 201 can give way to the shovel 30, it is effectively avoided that the shovel 30 collides with the slider body 20 when it is lifted or lowered. That is, after the slider body 20 completes the mold closing, the shovel 30 is located on the side of the slider body 20 away from the mold 40 and does not contact the slider body 20; this not only improves the service life of the shovel 30 and the slider body 20 and reduces the subsequent maintenance cost, but also completely prevents the shovel 30 and the slider body 20 from colliding during the mold closing process.

[0041] What needs to be explained here is that Figure 1 and Figure 7 , Figure 8 As shown, in this embodiment, the insert fixing blocks 24 on the slider body 20 are preferably set to two, and the number of insert fixing blocks 24 on the mold 40 body is set correspondingly. In other embodiments, the insert fixing blocks 24 on the slider body 20 can be set to one, three, or even more, which can be adjusted according to actual production needs.

[0042] like Figure 1 As shown, the slider body 20 is slidably fitted in the sliding groove 101 on the guide seat 10, and guide blocks 22 are provided at the bottom of the two opposite sides of the slider body 20. The sliding groove 101 is provided with guide grooves 102 on the two opposite groove walls that are slidably fitted with the guide blocks 22 to guide and limit the slider body 20.

[0043] like Figure 2 to Figure 6As shown, linkage grooves 202 for sliding cooperation of the linkage block 21 are provided on the groove walls on opposite sides of the avoidance groove 201, and a limiting block 211 with a cross-section larger than that of the linkage block 21 is fixedly connected to the rear end of the linkage block 21. A limiting groove 203 communicating with the linkage groove 202 and for sliding cooperation of the limiting block 211 is provided on the avoidance groove 201, and a pressing spring 23 is installed in the limiting groove 203, and the pressing spring 23 contacts and presses the limiting block 211, so that the linkage block 21 has a tendency to extend out of the linkage groove 202 and contact and cooperate with the back mold surface 322 of the shovel machine 30.

[0044] like Figure 2 to Figure 8 As shown, the shovel 30 has a fixed portion 31 fixed to the injection molding machine and an actuating portion 32 fixed obliquely to one end of the fixed portion 31, and the fixed portion 31 and the actuating portion 32 are similar to a 7-shaped structure. The actuating portion 32 is provided with a reset guide surface 323 for sliding the linkage block 21 on both sides of the mold surface 321.

[0045] like Figures 4 to 9 As shown, after the slider body 20 completes the mold closing, the reset guide surface 323 and the end of the linkage block 21 are in relative positions, and the shovel 30 is controlled to move downward so that the reset guide surface 323 contacts and presses the linkage block 21 and slides away. The top pressure spring 23 is compressed, and the linkage block 21 is retracted into the linkage groove 202. Then the shovel 30 moves downward smoothly. During this process, the two sides of the actuator 32 block the notch of the linkage groove 202, and the linkage block 21 is always located in the linkage groove 202.

[0046] like Figure 7 to Figure 10 As shown, when the actuating portion 32 of the shovel machine 30 contacts and presses the mold surface 321 and the bottom of the avoidance groove 201, the two sides of the shovel machine 30 give way to the notches of the linkage groove 202, and the top pressure spring 23, under the action of the elastic force, pushes the linkage block 21 to extend out of the notch of the linkage groove 202, so that the linkage block 21 and the actuating portion 32 are in contact with the back mold surface 322. At this time, the shovel machine 30 contacts and presses the mold surface 321 and the bottom of the avoidance groove 201, and the shovel machine 30 is reset to the initial position. Then, the shovel machine 30 is controlled to move upward, which can drive the slider structure to slide in the direction away from the mold 40 to complete the mold opening action.

[0047] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
